Networking Devices in Telugu
Hey,Guys here we are going to discuss networking devices
Network Basics:
a network is used to connects devices such as mobile phones,computers,peripherals....etc to establish the connection we need network devices such as switches,routers,and wireless access points.
Uni-cast: One to one communication Ex: Walkie talkie
Multicast: One to many communication Ex: Mobile
Broadcast: One to all or anyone communication Ex:TV Communication
Uni-cast: One to one communication Ex: Walkie talkie
Multicast: One to many communication Ex: Mobile
Broadcast: One to all or anyone communication Ex:TV Communication
Switches:
switch is fundamental network device,this is used communicate each other in the network such as printers,servers,and computers.switches are intelligent device it can store MAC address & Cam tables.
Benefits:
✔Communication:we can establish network connection for all devices.
✔File sharing : we can share resources in the local network free of cost.
✔Full duplex:Two way communication at the time.
✔Uni-cast:one to one communication
Basically,Switches are divided into two types are 1.Unmanageable & 2.Manageable
Every networking device works on TCP/IP Layers. TCP stands for transition control protocol
it defines how devices exchange data over the internet.
In the TCP/IP there are four model layers are there
Transport Layer:It provides error-free communication between end systems,it divide into into segments and it controls the flow of data.
Internet Layer:It is responsible for delivering packets between sources and destinations, Know a days IPv4 mostly using why because IPv6 new technology but not suitable for some devices.Example: IP(internet protocol),ICMP(Internet Control Message Protocol),ARP(Address resolution Protocol)
Network Layer:Network layer is the combination of new layers there are Data link layer and Physical layer
Protocol:It has set of rules and regulations.
TELNET: It is a 2 way communication protocol,which allows remote access and run application on it.
FTP: It stands for file transfer protocol,it has 21 port number, it is used to transmit files over network
SMTP: It stands for simple mail transfer protocol, it has 465 for TLS & If you're using SSL 587, It is out going protocol.
ARP: It stands for address resolution protocol,used for identify the mac address through IP.
RARP: It stands for reverse address resolution protocol,used for identify the mac MAC address through MAC.
ICMP: It Stands for Internet Control Message Protocol,used to check error reporting in the network
Ping is the best example for ICMP
✔Full duplex:Two way communication at the time.
✔Uni-cast:one to one communication
Basically,Switches are divided into two types are 1.Unmanageable & 2.Manageable
Unmanageable switch:
an unmanageable switches are unable to configure but low of cost,so most of small organisations prepares it.
Manageable switch:
an manageable switches can be configured means we can configure remote access,port blocking,URL blocking...etcRouters:
Routers connect multiple networks together means private(LAN) and public(WAN) networks,Router works as per routing protocols & it select shortest path in the communication.
Routing protocols :
✅ RIP-(Routing Information Protocols)
✅ IGRP-(Interior Gateway Protocol)
✅ BGP-(Border Gateway Protocol)
✅ IS-IS-(Intermediate System-to-intermediate System)
✅ OSPF-(Open Shortest path First)
✅ OSPF-(Open Shortest path First)
✅ EGP-(Exterior Gateway Protocol)
✅ EIGRP-(Enhanced Interior Gateway Routing Protocol)
Modulation:Convert analog signal to digital signal
Demodulation: Convert digital signal to analog signal
Modems:
Basically, Modems are used for Modulation & Demodulation it meansModulation:Convert analog signal to digital signal
Demodulation: Convert digital signal to analog signal
Repeaters:
It is used for increase the strength of signalsNIC:
NIC stands for Network Interface Card,it is the primary device in the networkEvery networking device works on TCP/IP Layers. TCP stands for transition control protocol
it defines how devices exchange data over the internet.
In the TCP/IP there are four model layers are there
TCP/IP Model Layers:
Actually,TCP/IP works one below four layers,TCP/IPv4 has 32 bit,
Each layer works on specific protocols.
Application Layer:In this layer applications exchange data each other as per using protocol,Its have TELNET, HTTP, FTP, POP3, SMTP, protocols
Transport Layer:It provides error-free communication between end systems,it divide into into segments and it controls the flow of data.
Internet Layer:It is responsible for delivering packets between sources and destinations, Know a days IPv4 mostly using why because IPv6 new technology but not suitable for some devices.Example: IP(internet protocol),ICMP(Internet Control Message Protocol),ARP(Address resolution Protocol)
Network Layer:Network layer is the combination of new layers there are Data link layer and Physical layer
Protocol:It has set of rules and regulations.
TELNET: It is a 2 way communication protocol,which allows remote access and run application on it.
FTP: It stands for file transfer protocol,it has 21 port number, it is used to transmit files over network
SMTP: It stands for simple mail transfer protocol, it has 465 for TLS & If you're using SSL 587, It is out going protocol.
ARP: It stands for address resolution protocol,used for identify the mac address through IP.
RARP: It stands for reverse address resolution protocol,used for identify the mac MAC address through MAC.
ICMP: It Stands for Internet Control Message Protocol,used to check error reporting in the network
Ping is the best example for ICMP
